Yau, interesting idea! Currently there is no way to do this using the
MarkupViewer. Of course this is all possible if you display the
rendered HTML in a browser, provided that the browser itself can work
with active help (it must be an internal browser, not external).

Do you want to be able to do this by having an image hyperlink in the
source markup or programatically?

I'm assuming that you're talking about active help
http://help.eclipse.org/help32/index.jsp?topic=/org.eclipse. platform.doc.isv/guide/ua_help_content_active.htm

There are a few missing things to make this work with MarkupViewer:

# MarkupViewer doesn't support image hyperlinks
# MarkupViewer doesn't run JavaScript

Please submit an enhancement request if this is of interest to you. Of
course contributions in this area would be appreciated!

Yau,

Image hyperlinks are now supported (see
https://bugs.eclipse.org/bugs/show_bug.cgi?id=257868)

to get hyperlinks invoking Eclipse commands is a little trickier, since
MarkupViewer doesn't run JavaScript. It is however possible, but
requires some subclassing. The following recepie should do the trick:

1. Subclass AnnotationHyperlinkDetector
2. Override AnnotationHyperlinkDetector.createHyperlink to return
hyperlinks that recognize your custom URL scheme, or pass off to super()
3. Subclass MarkupViewerConfiguration
4. Override createAnnotationHyperlinkDetector() and cause it to return
your subclass from #1

That should do it. Please let me know how it goes.

David
